Hi all, I have just finished fitting a 2nd hand HF SB250RC BARRETT TRANSCEIVER.
I can hear all over AUS at times, but when I try to make contact I get no response. The question is- when I transmit, should something come up on the LCD display like a bar graph. this is what my UHF does- next to the T.X. digits. Also when I am speaking in to the hand piece-I can still here other people talking as well. Is this normal? Because with my UHF radio when the ptt is held down the conversation is cut off. It is the first time I am trying to use this thing, so I dont know if it is working correctly or I am doing something wrong. The unit is like brand new-no scratches any where. Antenna mast is a TERLIN 24 tap. An.y info would be much appreciated, cheers.

The radio is not switching into tx mode for some reason. I'm not familiar with the radio, dunno if it has some lock to prevent accidential transmissions or not. Could be a bung wire in the mic or the tx switching either mechanical or diode not operating.My Best Mates

Thanks Mad Dog Morgan, I now recon the radio is'nt switching to T.X mode, as the bright red light doesn't alter when talking. I hope it is'nt a diode-could be expensive. I am getting 12.7 volts to the transceiver & have a 30AMP HRC fuse at the battery. I would like to check the power draw when transmitting, but my multimeter can only go up to 10 amps.

No not a serious problem and shouldn't be expensive at all but it needs someone who knows what they're doing to have a look at it.My Best Mates

Carazy, check the microphone is plugged in correctly as they can vibrate loose in the socket. Check you are not on a "User Programmable Channel" as you can only recieve on these channels, not transmit. There is a red LED on the control panel which will glow when the set is on, but when transmitting is intensity will vary depending on how you are talking. Contact Barrett in Perth and ask for a manual.

Darryn, the microphone can't be disconnected, however the speaker you can disconnect. I have entered the VKS-737 BASES as follows-channel 150-3995.0khz, 148-11612.0khz, 147-8022.0khz, 146-5455.0khz I don't
know if these are " User Programmable Channels". The red light does glow, but does not change its brightness at all & I have only just noticed that above it, there is a T.X. abbreviation there. I thought it was just for power is on. I was planning to go see somebody, but thought I may ask here first-you never know! Thanks for the info.

Errol, I mostly listen in on the chanel 2 (8002) freq ok, interesting & informative. I will join the VKS-737 org, just as soon as I find out my HF radio works ok & I haven't brought a dud! I plan to travel all over aus so I recon I will be needing it. I will listen out for you guy's, but I can't seem to pick up Perth-if your in that area. I don't know if Im too close, as Merredin is only 270km away. Like the rig set up-a few bucks hey!
